MEASURE WATER FLOW

You need to determine the available water flow for your sprinkler system so you'll know

ow many sprinkler heads can run at one time. Water flow is measured in gallons per minute

h
or GPM.

Measure Your Water Pressure

• Attach an Orbit®pressure gauge (part #
53020, 91130) to an unregulated outside
faucet*. Unregulated means a line without

a pressure regulator.

• Open the faucet and record the reading
on the gauge. No water should be running

during the test.

PSI _________

Measure the Main Water Service Line

• Wrap a piece of string around your main

ater service line then measure the length

w
of the string.

• Use the table to convert the string length
to pipe size (diameter).

3

Note: The main water service line is the pipe that runs from
the water meter to the house. If you're connecting to a line
other than the main line, measure the line that you will be
connecting to.

Pipe Size _________

GPM Capacity ___________

* If an unregulated faucet is unavailable, call the local water district for an estimated PSI.

ystem Capacity

S

Use the main
line pipe size
and pressure
(PSI) taken to
determine the
gallons per
minute (GPM)
capacity of your
system.

4

Important: If your water pressure exceeds 80 PSI, use a pressure reducer

. Excessive pressure may damage system.

PLAN HEAD PLACEMENT

Head to Head Coverage

Proper sprinkler placement allows even watering and
reduces dry patches.

Proper placement requires:

• Head to head coverage: Each sprinkler should spray
to the head beside and across it.

• Equal spacing between heads: Permits uniform water
distribution.

Placement Example: Good

• Good Overlap

• Head to head coverage

Placement Example:

There is not enough overlap. The center is not
getting water.

• Not enough overlap

• No coverage in center

Place Heads in Corners

• Begin by placing a sprinkler in

• Use a compass to draw the

CREATING WATERING ZONES OR STATIONS

A watering zone or station consists of a group of sprinklers attached to one valve.
The number of heads per zone will be determined in this section.

Purpose of Zones

Zones are designed to:

• Maintain adequate water flow for optimal spray coverage (Avoid dry patches)

• Separate areas based on watering requirements

- Shade vs. Full Sun Areas

- Lawn vs. Shrubs

Important:

• Do not mix sprinkler types in the same zone (e.g. Gear Drive, Impacts, Pop-Ups and Bubblers)

• Do not exceed the maximum sprinkler heads recommended per zone

• Use the recommended pipe size in this guide. Smaller diameter pipe will decrease the water flow.

Group Heads of Same Type in the Same Area

Starting with large area heads, use the following
example as a guide.

• Identify all large area heads on
your drawing.

Example – We have determined that our home

more than three Voyager II

STEP 2: Identifying Sprinklers in a Zone

Begin grouping large area heads, ensure you do not ex­ceed your “Maximum Heads per zone number.”

Example – Since we determined (in our example above) that 3 Voyager II®heads
is the maximum zone capacity, we grouped all large area heads into 2 zones.

Step 3:

Medium and Small Area Head Zones

Repeat steps 1 & 2 to determine and identify zones for Medium Areas Heads. Repeat again for
Small Area Heads.

Valve Manifold Location

One valve will be used for each zone. Valves that are grouped together are called a manifold.
It’s common to install one manifold in the front yard and one in back.

Mark the Location on Your Plan

Tip: The valve manifold(s) should be installed in an accessible location, away from heavy foot traffic, where it is easy to operate
and service. It's also a good idea to locate the manifold on elevated ground, to avoid water accumulating around the valves.

Plan Backflow Prevention

A backflow prevention device is used to stop foreign material from siphoning back into the
main water supply. The local code information you gathered from your water district should
include the type of device to install and where and how it should be installed. Plan a location
for your backflow prevention device and draw it on your layout.

9

Lateral lines – Pipe that branches off from the header line and supply water to the sprinkler heads

• Do not use pipe smaller than 3/4"

Good Layout Example

This is a good layout because the water is evenly distributed
between the lateral lines and individual sprinklers.

Bad Layout Example

This is a bad layout because there is no header line. The
sprinkler heads, located at the end of the line, will have less
water pressure than the heads located closer to the valve.

• Unplug your timer from the power source (if hard wired
turn off appropriate breaker switch or remove fuse).

• Connect each colored sprinkler wire to a separate
numbered terminal (on the timer).

• Connect the white (common) wire to the common

• Restore power to your timer.

• To test proper wiring, manually run each station
